Solve the math problem.

12 . keep going.

1x - 5 = 9
1x = 9 + 5
1x = 14 (divide both sides by 1 to get x)
1x/1 = 14/1
x = 14

 

[Perception]

1x - 5 = 9
1x = 9 + 5
1x = 14 (divide both sides by 1 to get x)
1x/1 = 14/1
x = 14

good job .

14! May I have something more challenging please? :O

One more for tonight, one of my favs.

Three guests check into a hotel room. The clerk says the bill is $30, so each guest pays $10. Later the clerk realizes the bill should only be $25. To rectify this, he gives the bellhop $5 to return to the guests. On the way to the room, the bellhop realizes that he cannot divide the money equally. As the guests didn't know the total of the revised bill, the bellhop decides to just give each guest $1 and keep $2 for himself. Each guest got $1 back: so now each guest only paid $9; bringing the total paid to $27. The bellhop has $2. And $27 + $2 = $29 so, if the guests originally handed over $30, what happened to the remaining $1?

Did somebody want the answer to this? I thought someone asked me. Maybe I missed it.

Set up your equations:
C = # of caviar
B = # bologna
L = # of liverwurst

C + B + L = 100
5C + 2B + L/10 = 100

multiply the 2nd equation by 10 and subtract the two
49C + 19B = 900

Now, there are lots of ways to do that, but you need both C and B to be integers. Notice that 900 is divisible by 10. Divide the whole equation by 10
$4.9 C + $1.9 B = $90

Now, we know she need to make exactly $90 selling just caviar and bologna. Each time she sells a sandwich, she'll have to give a dime in change. To get back to an exact dollar figure, she'll need to sell some multiple of 10 sandwiches. So, make the substitution

C + B = 10 n

Now, solve for C and substitute
49 n - 3 B = 90

Remembering that n and B are both integers, n must be a multiple of 3 (divide that equation by 3 and see). So try, n=3, 6, 9, etc.
For n=3, B = 19
For n=6, B = 68
For n=9, B = 117 (which is impossible.)

If B = 19, then C = 11 and L = 70.
If B = 68, then C = -8 which is impossible.​

edit: oh lol it's a diffrent one every time. hold on i will find the last one.

x = 9 - 5
x = 4

next time give me a challenge...

You just picked the easiest one! Look at the last few pages for a challenge! Or better yet, let me give you one! xd

 

[Deathwink]

4
x + 5=9
4+5=9
x=4

the answer is 4

 

[riley freeman]

Damn so many smart people, too bad i'm the king of smart

you sleep 8hours a day(24 hours), how many years have you slept in 30 years solve that

yes yes sorry i thought there was only the first question.

lol, a classic one.

first the guests pay 30$ to the clerk, after that the clerk give 5 dollar refund to the bellhop. so the clerk has 25$ and the bellhop has 5$. the bellhop gives 1 dollar to each guest as refund so the clerk has 25$ and the bellhop 2$ and the guests 3$. saying that 9 * 3 = full payment is wrong, 9 * 3 only equals what the clerk got plus what the bellhop got (25$ + 2$). the full payment is what the clerk got plus what the bellhop got plus the guests refund. so 25$ + 2$ + 3$ = 30. the 9 * 3 is the misleading part here, it's not a viable equation to calculate the 30$ with, only the 27$ which is the clerk plus bellhop

Damn so many smart people, too bad i'm the king of smart

you sleep 8hours a day(24 hours), how many years have you slept in 30 years solve that

24 * 365 * 30 = 262800 hours in 30 years
8 * 365 * 30 = 87600 hours in 30 years

262800 - 87600 = 175200 hours

in 30 years you sleep 175200 hours.

edit: wait years lol.

175200 / 24 = 7300 days
7300 / 365 = 20 years

in 30 years you sleep 20 years

Alright EnDash, how about some simple Calculus? I want you to find the area of two lines wrapped around the line x = -2.
Here are the equations: y = x + 2 and y = x^2

If you need any help on how to do this, just let me know! :O

lol, i had a blackout from 7th grade to 12th grade so i can't gurntee i won't do embarrasing mistakes, but i will try my best

eq1: y = x + 2 so this is a linear line
eq2: y = x^2 so this is a parabola
the first line is x = -2 which is a straig line (x is constant, y changes), so i need to find the intersections of all 3 lines

eq1: y = -2 + 2 = 0 is inter1
eq2: y = -2 ^ 2 = 4 (god i hope this is correct) so this is inter2
the parabola with the linear line is complicated a bit, there are 2 intersection points, each has the same y for both equations so

x + 2 = x ^ 2, i don't remember how to solve this but the calculator gives x = -1, x = 2
we can put x in one of the equations to get y:

y = -1 + 2 = 1
and point 2 is y = 2 + 2 = 4

so we have 3 intersection points
p1: x = -2, y = 0
p2: x = -2, y = 4
p3: x = -1, y = 1 or x = 2, y = 4

i have no idea how to calculate the area from this. so i give up here lol, if anyone wants to take over please do Zzz

Not even close! Here is the first thing you need to do: You need to set both equations equal to each other and solve for x. The numbers you get will be your intervals. You will need them to set up an integral. Do that and then I will show you how to set up your equation. xd
